Abstract
Embodiments described herein may include at least one pole including a plurality of projections disposed at incremental heights along the pole, an object, a first pulley positioned on a first side of the object, and a second pulley positioned on the second side of the object.
Description
This application claims a benefit of priority under 35 U.S.C. §119 to Provisional Application No. 61/880,299 filed on Sep. 20, 2013, and is a continuation of U.S. Ser. No. 14/339,878 filed on Jul. 24, 2014, which and fully incorporated herein by reference in its entirety.
Field of the Disclosure
Examples of the present disclosure are related to systems and methods that effectively and efficiently raise an object to a desired height. More specifically, as the object descends from a raised height, the object may provide energy that may be converted to an electric power by an electric generator.
Background
Potential energy is the energy of an object or a system due to the position of the object relative to a surface. Gravitational energy is the potential energy associated with gravitational force, where potential gravitational energy is obtained by elevating the object against Earth's gravity away from a surface of the earth. Factors that affect an object's potential gravitational energy include: the object's height respective to a reference point or Earth's surface, the object's weight, and the strength of the gravitation field it the object is in. Responsive to the object descending from a raised height towards the Earth's surface, gravity accelerates the mass of the object, and the potential energy is converted into kinetic energy. The kinetic energy may then be used to perform work or generate electricity by an electric generator.
In certain parts of the world, alternative energy sources such as gravity, solar, wind, and fossil fuels may be the only viable source of energy to individuals. However, the costs or creating solar or wind energy generators may be too high to construct. Similarly, purchasing fossil fuels may be too expensive. Further, solar energy is only available at night if power is stored in a battery, and wind power may only be available during certain parts of a day and/or year.
However, there is a need of cheap, reliable energy for electric lighting and other electronic devices that have no way to connect to an electrical power grid.
Accordingly, needs exist for systems and methods to generate electric power from gravity.
Embodiments disclosed herein describe systems and methods for efficiently and effectively raising an object to create potential energy, and converting the potential energy into electric energy.
Embodiments may include at least one vertical pole, shaft, vertically extending structure (referred to hereinafter individually and collectively as “vertical pole”), wherein the vertical pole includes a plurality of projections or fulcrums (referred to hereinafter individually and collectively as “projections”). The plurality of projections may include sets of projections extending out of different sides of the vertical pole, and the sets of projections may be disposed at incremental heights along the vertical pole. In embodiments, a first set of projections may be positioned below a second set of projections along the vertical pole.
Embodiments may also include a carriage, an object supported within the carriage, a first pulley positioned on a first side of the carriage, and a second pulley positioned on the second side of the carriage. The carriage may be supported by a first set of projections, responsive to the first pulley applying force to the carriage, the carriage may tilt in a first direction, and a first pinion coupled to the carriage may interact with a second set of projections along the vertical pole. Next, the second pulley may apply force to the carriage, the carriage may be tilted in a second direction, and the pinion coupled to the carriage may interact with the second set of projections of the vertical pole to raise the carriage to the second set of projections. This process may be repeated until the carriage is at a desired height.
In embodiments, the amount of energy needed to tilt the carriage to be raised to the next set of projections may be based on the height of the carriage, the weight of the carriage, positioning of the first and second pinions, and the placement of the projections on the vertical pole.
Responsive to the object being tilted in a first direction, a first side of the carriage may be raised to a height determined by the distance between the lower and upper projections and the physical height of the object. Responsive to the pinions of the carriage being positioned on different sets of projections that are positioned at different heights on the vertical pole, the center of mass of the carriage and the object supported and contained within the carriage may be shifted, such that the object may assist in raising the carriage to the next set of projections. A maximum force to tilt is realized when the pinions are moved to the maximum width of the object and decreased as the pinions are moved to the center of the objects width. The placement of the pinions establishes two fulcrum positions along the base of the carriage and determines tilting support points of the carriage.
In embodiments, if the height of the object is increased and/or the width of the object is decreased, or the spacing between the pinions are decreased, the distance the carriage is able to be raised may decrease, while also decreasing the amount of energy needed to tilt the object. In embodiments, based on the shape and/or size of the object and the placement of the pinions, different distances between the sets of projections may be desired or required. The placement of the pinions determines the height that the base of the carriage will be vertically lifted when tilted and the maximum angle of tilt before the object will tilt over under the influence of gravity.
In embodiments, once the carriage is at a desired height, the carriage may be lowered and the potential energy that the object possesses may be transferred to an electric energy converter and converted into electrical energy. To this end, embodiments may be configured to allow a single individual or a plurality of individuals to efficiently raise a heavy carriage to a height to produce enough potential energy that may be converted to electrical energy.
In embodiments, to increase the amount of potential energy that may be obtained from the raised object, the height of the vertical pole may be increased, the weight of the object may be increased, and/or the number of lifting systems may be increased. Therefore, individuals may be able to generate sustainable electrical energy using embodiments that are configured to raise an object by changing the center of mass of the object, such that the object aids in lifting itself up.
In embodiments, the placement of the projections may determine the vertical distance that the carriage may move vertically when the object is tilted. More projections may be placed on the vertical pole than needed so as to take into account a partial tilt, thus providing a holding place for the pinions. Projection spacing along the vertical pole are determined by the design of the carriage and the location of the two fulcrum positions along the base of the carriage, which determines the maximum tilt angle of the carriage.
In embodiments, a plurality of vertical poles may be coupled together by coupling a drive shaft from a first gear box of a first vertical pole to a second gear box of a second vertical pole. By raising a first carriage associated with the first vertical pole and a second carriage associated with the second vertical pole the total potential energy of the first and second objects may be converted into kinetic energy. Therefore, the first and second gear boxes may be configured to increase the amount of converted electrical energy generated by a plurality of vertical poles.

The spacing between a first set of projections 112 and a second set of projections 112 may be determined by empirical evidence based on the height and width of carriage 120 and the distance between the contact point of pinions 125 with the projections 112 on the vertical pole 110. carriage Further, the distance between the first set of projections 112 and the second set of projections 112 may be based on the angle of tilt determined by the vertical distance the base of carriage 120 is raised from a horizontal position at the point where the pinions 125 touch the projections 112 along the vertical pole 110. The point where pinions 125 make contact and is supported by projections 112 on the vertical pole 110 determines the two fulcrum points along the base of carriage 120. These two fulcrum points are used in the calculation of the angle of tilt and the force required to tilt. The amount of force required to tilt carriage 120 from the first set of projections 112 to the second set of projections 112 is determined by the height of carriage 120 and the weight it carries as well as the width of carriage 120 and the placement of the pinions 125.
Each side of carriage 122 may include pulley system receivers 124. Responsive to a first cable 131 of first pulley system 130 being pulled to lift carriage 122, the resultant force applied to a first pulley system receiver 124 may raise a first side of carriage 122. Responsive to a second cable 141 second pulley system 140 being pulled to lift carriage 122, the resultant force applied to a second pulley system receiver 124 may raise a second side of carriage 122. Therefore, carriage 122 may be raised to a first set of projections 112 by tilting carriage 122 in a first direction, which may change the center of mass of carriage 122. Carriage 122 may then be tilted in a second direction, and the change in the center of mass of carriage 122 may be configured to assist in lifting carriage 122 to the first set of projections 112.
In embodiments, carriage 122 may also include a drop cable lift ring 127. Drop cable lift ring 127 may be configured to be coupled to electric generator 150 via a drop cable 151. As carriage 122 descends, the drop cable may cause torque to electric generator 150 to convert to kinetic energy of the descending carriage to electric power.
Pinion movement restrictors 126 may be devices configured to restrict the movement of pinion 125 so as to support the carriage in place on projections 112. In embodiments, if the pinion movement restrictors 126 are set in their restrictive position, the carriage 122, may not descend vertical pole 110. Once the pinion movement restrictors 126 are unset, carriage 122 may descend vertical pole 110.
At operation 210, the pinions on both sides of a carriage may be supporting the weight of the carriage on a first set of projections. Further, the carriage may be substantially level, and positioned on an upper surface of the first set of projections on a vertical pole. As depicted at operation 210, a substantially similar amount of the block module may be positioned on a first side of the vertical pole as the amount of the block module positioned on a second side of the vertical pole. Operation 210 may be performed by a lifting system is the same as or similar to lifting system 100, in accordance with one or more implementations.
At operation 220, force may be applied to a first side of carriage to tilt the carriage in a first direction. Responsive to the force being applied to the first side of carriage, a first pinion may be positioned above a second set of projections, and a second pinion may be positioned above the first set of projections. In embodiments, once an initial amount of force is applied to the carriage to tilt the carriage, the center of mass of the carriage may be changed, and the weight of the carriage may be utilized to position the first pinion above the second set of projections. Therefore, in addition to the force applied to tilt the carriage, the physical dimensions of the object may be utilized to lift the carriage. Operation 220 may be performed by a lifting system the same as or similar to lifting system 100, in accordance with one or more implementations.
At operation 230, force may be applied to a second side of the carriage to tilt the carriage in a second direction. Responsive to the force being applied to the second side of the carriage, the second pinion may be positioned above the second set of projections, and the second pinion may be positioned above the second set of projections. In embodiments, once an initial amount of force is applied to the carriage to tilt the carriage in the second direction, the weight of the carriage may pivot around the second set of projections on the first side of the carriage, and the weight of the carriage may be utilized to position the second pinion above the second set of projections. Therefore, in addition to the force applied to tilt the carriage, the weight of the carriage pivoting around the second set of projections may be utilized to lift the carriage. Operation 230 may be performed by a lifting system that is the same as or similar to lifting system 100, in accordance with one or more implementations.
One skilled in the art may appreciate that operations 220 and 230 may be repeated to raise the carriage to different heights on vertical pole to increase the potential energy of the carriage. Furthermore, one skilled in the art may appreciate that the direction of the force desired to tilt the carriage in operations 220 and 230 may be reversed.
Although the present technology has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred implementations, it is to be understood that such detail is solely for that purpose and that the technology is not limited to the disclosed implementations, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present technology contemplates that, to the extent possible, one or more features of any implementation can be combined with one or more features of any other implementation.
As depicted in FIG. 3 , a first set of block modules 123 is positioned on a first side 305 of carriage 122, and a second set of block modules 123 is positioned on a second side 310 of carriage 122. Vertical pole 110 may be positioned at the center of carriage 122, and carriage 120 may be positioned above a first set of projections 112. In embodiments, pinions 125 may be positioned adjacent to and over the first set of projections. Elements depicted in FIG. 3 may be the same as those depicted in FIG. 1 .
As depicted in FIG. 4 , a plurality of projections 112 may be positioned at even intervals along vertical pole 110. As carriage 122 is tilted in the first direction and then the second direction, carriage 122 may be positioned at a higher set of projections 112.
As depicted in FIG. 5 , first pulley system 130 may be positioned on a first side of frame 105, and second pulley system 140 may be positioned on a second side of frame 105. First and second pulley systems 130, 140 may include a rocking cord guide wheels that are configured to guide the cords, cables wires, etc. of first and second pulley systems 130, 140 when the cords are pulled. Frame 105 includes drop cable guide wheel 520 that is configured to guide a cable coupled to electric generator 150 and carriage 122, such that as carriage 122 descends the coupled cable can be guided.
Furthermore, frame 105 may include a plurality of wire tie offs 515, where cords, cables, wires, etc. may be used to anchor the system 100 to ground anchor points so as to stabilize system 100 when raising a carriage 122 up vertical pole 110.
As can be appreciated by lifting system 700, the rocking cords, drop cable guide wheels, and guide wire tie offs may be placed in different positions within the frame of lifting system 700. Therefore, different mechanical configurations may be obtained to enhance ease of operation.
The cable assist lines 880 may be threaded through an upper support and guide assembly at the top of the vertical support (not shown). Cable assist lines 880 may in turn be threaded through pulleys 890, and pulleys 850 coupled with the pulley support assembly 835, and lever assist arms 840. The pulley support assembly 835 may be configured to slide up and down the vertical pole 110 as the carriage 820 moves vertically up or down. The pulley support assembly 835 attaches to the bottom center of the carriage 820. Pulley 850 may be coupled to carriage 820, allowing carriage 820 to move freely. In embodiments, pulley support assembly 835 may be configured to remain level while carriage 820 tilts.
In embodiments, the ratchet pinions may be configured to roll in only one direction while the carriage assembly is tilted back and forth. Once the block is to the height desired, the ratchet pinions direction of rotation is set in reverse so as to allow the carriage 1005 to slide back down the vertical support rack. At the top of the carriage is a pulley support assembly 1015. The pulley support assembly 1015 slides up and down the vertical pole 110 as the carriage 1005 moves vertically up or down. The pulley support assembly 1015 attaches to the bottom center of the carriage 1005 and provides for placement of additional pulleys and stability of carriage 1005
The carriage 1110 is held at its two fulcrum points by supporting arms 1115 which are in turn supported by two vertical support screws 1120. The support arms 1115 are moved up and down by the turning action of the vertical support screws 1120. The vertical supports are acted upon by the mechanics at the top of the lifter. Similar to other embodiments, the tilting mechanism moves back and forth causing the carriage 1110 to tilt through a tilt cycle. As the carriage 1110 is tilted to one side the vertical support screw 1120 opposite the direction of tilt turns and raises the supporting arm up to meet the bottom of the tilted carriage 1110. Upon reversing the carriage 1110 tilt direction, the process is repeated, allowing the other support arm to move up to the bottom of the Carriage.
This implementation may increase stability due to being supported by two arms 1115 extended from the vertical support screws 1120. Furthermore, the gears needed to turn the vertical support screws 1120 and the tilting mechanisms are easily operated from a central rotating shaft, which is ideal for a wind powered source. This allows for gearing up or down the force transferred, easily matching the tilting and turning power requirements of lifting system 1100. Like other lifting systems, a method must be incorporated to release the ratchet gears on the tilting arms and the vertical support screws 1120 from the vertical support arms 1115 so as to allow the carriage 1110 to descend.
A lifter upper cross bar 1240 is shown in this embodiment with rocking cables 1245, used for ground based input, but could be replaced with a rocking assembly which might be attached to some mechanical assembly using some other power source. In embodiments, the weight and carriage 1220 may be allowed to drop back down the vertical support pole 1235 to obtain the potential energy of the raised object.
